Saw the old Metropolis (IMDB:0017136) movie -- very cool! The first Science Fiction movie, released in 1927. And already we find many ideas in this movie that have been taken up by later movies:
I had seen the Giorgio Moroder restored version a long time ago -- I must have been around 13 back then, and some of the images impressed me very much. Seeing the worker straining to align the pointers of a watch-like machine with glowing lamps or the crazy Maria leading the crowd through the city -- the images stayed with me and watching the new restored version of the movie was time well spent.
